Four main Dynamic Stability definitions should be discussed, although a significant overlap is present among them. From the viewpoint of mechanics, the most important one is Lyapunov stability and the related Lyapunov second method (LSM). This is suitable for non-linear systems. It can be employed for the investigation of the most general theorems as well as for the investigation of particular systems. As the second definition should be stated stability of the linear systems, where Routh-Hurwitz (RH) or Silvester determinants are the most popular approaches. Both of these definitions have a number of reduced variants that are suitable for special classes of problems.
